Hail Fredonia: Groucho in Duck Soup

President Rufus T. Firefly: I'd be unworthy of the high trust that's been placed in me if I didn't do everything in my power to keep our beloved Freedonia in peace with the world. I'd be only too happy to meet with Ambassador Trentino, and offer him on behalf of my country the right hand of good fellowship. And I feel sure he will accept this gesture in the spirit of which it is offered. But suppose he doesn't. A fine thing that'll be. I hold out my hand and he refuses to accept. That'll add a lot to my prestige, won't it? Me, the head of a country, snubbed by a forgein ambassador. Who does he think he is, that he can come here, and make a sap of me in front of all my people? Think of it - I hold out my hand and that hyena refuses to accept. Why, the cheap ball-pushing swine, he'll never get away with it I tell you, he'll never get away with it! [Trentino (Louis Calhern) enters] So, you refuse to shake hands with me, eh?
(Firefly slaps Trentino with his glove for the second time in two days and the war begins)
